Specification of Letters Patent. Patented Aug. 2'7, 1912. Application filed June 28, 1909. Serial No. 504,806.

To all whom it may concern:

Be it known that I, JEROME N. HUM- PHREYS, a citizen of the United States, resid ing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Ap aratus for Chillin and Whitening Lard ompounds; and I o declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to im rovements in apparatus for chilling and w i'tening lard compounds.

The object of the invention is to provide a machine or apparatus of this character by means of which the operation of chilling and whitening lard compounds will be simplified and improved and the product hardened or stiffened to such a degree as to require the addition of a less quantity of high priced stiffening agents and thus reducing the cost of producing the compound.

A further object is to provide a machine of this character having an improved means by which the cooling agent is applied to the compound and to provide for a maximum amount of cooling and rubbing surface.

With the foregoing and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

is a longitudinal vertical sectional view of a coolin and bleaching apparatus constructed in accordance with the invention; 2 is a cross sectional view on the line 2-2 of Fig. 1; Fig. 3 is a side view of the inner brine linderof the machine. In the em ocliment oi the invention, 1 prouide snoutercylinder 1 which is surrounded hya duid tight "Eacket 2. The ends the cylinder It Md jacket 2 are secured to heads 3 in any suitable manner to form a fluid. tight joint therewith. The space 4: between die. cylinder 1 and the jacket 2 is ads. ted to receive cooling agent which is predictably in the iiorm of. brine which is let into the space through an inlet port 5-and is discharged from t space through an outlet port #6.. The posits 5 and. 6 are arran at opposite ends of the jacket or a. 2

in the accompanying drawings, Figure 1' thereby providing for'a circulation of brine throughout the entire len h of the space 4 between the cylinder 1 an the jacket 2.

In the outer cylinder 1 1s revolubly mounted an inner brine containing cylinder 7, said cylinder being provided atits opposite ends with heads 8 on which are formed tubular bearin extensions or trunnions 9 which are revo ubly mounted in bearings 10 formed in the heads 3 of the outer cylinder and jacket. The heads 3 are also provided with stufiing boxes 11 throu h which the tubular trunnions pass there y forming a fluid tight joint between the trunnions 9 and the bearings it; the heads 3. In the outer ends of the tubular trunnions 9 are arranged stufling boxes 11 which form fluid tight connections for the brine inlet and discharge pipes 12 and 12' which are connected with the trunnions to supply the cylinder 7 with brine or other form of cooling agent. The cylinder 7 is of somewhat less diameter than the cylinder 1, thus providing between said cylinders a thin annular space 13 throu h which. the lard compound is forced in te operation of cooling and whitening the same. The lard compound is let into the space 13, at one end of the apparatus, through an inlet port 14 formed 1n one of the heads 3 and is discharged from said s ace through a dischar e port 15 formed in the opposite head 3. are preferably provided with irregular cooperating surfaces to provide for an increased cooling area and also to provide increased rubbing suriace whereby the com-' pound, when being forced through the passage 13, will be thoroughly rubbed, intermlxed and aerated by the rapid rotation of the inner cylinder 7, which action will whiten the'compound to a higher de ree and impart to thesame a whiter color t an is obtamable by any other method. ihis rubbing between the irregular surfaces forming the walls out the-space or passa e through which the compound passes w also impart to the compound a flaky quaiity and will also harden or stifi'en the same so that it is necessaryto use a much smaller quantity of high priced stidening agents, such as oleo-stearin or other beef fats, thereby greatly reducin the cost of manufactun mg or producin t e compound. I

ihe irregular suriace of the Inner cylinder 7 and outer cylinder. 1 may tie-formed m ilo any desired manner, but is here shown and referably' formed by constructing the 'cyllnders with a series of annular grooves or channels 16 and 17 the grooves or channels'17 of the outer'cylinder fitting into thegrooves or channels 16 of theinnercylinder,

thus providing an irregular or tortuous assage between the cylinders through w 'ch the lard compound is forced and thoroughly rubbed and co'oled in the manner hereinbe-' supports 18 arranged below the heads 3.

The inner cylinder 7 has mounted on one of its trunni0ns 9, tight and loose pulleys: 19 by means of which-suitable power is applied to, the cylinder to rapidly revolve the same.

In Fig, 2, the outer casing 1 is shown as being constructed of two halves and each provided with clamping flanges. This illustration, of course, is a conventional one and is made only for the purpose of showing the obvious means of connecting the parts together.

From the foregoing description, taken in connection with the accompanying drawings, the construction. and operation will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.
